Radio X, referred to as RADIO:X in its logo, is an alternative rock/heavy metal/grunge music station in Grand Theft Auto: San Andreas. It is hosted by Sage, an escaped mental patient who holds extremely pessimistic world views. A proud member of Generation X, she is very outspoken against the previous generation and constantly speaks her views on air between songs, even expressing her dislike of cartoons. Tommy "The Nightmare" Smith, host of classic rock radio station K-DST, tends to hold a rivalry with Sage. In fact, on air, Smith tells her to "get over it!" during the intro to Runnin' Down a Dream, which is ironic because Sage states on Radio X that she "slept with this guy once" before Guns N' Roses' hit Welcome to the Jungle (which Smith's voice actor Axl Rose was credited to creating) commences.
